    摘要: A nematic liquid crystal device for electro-optical display devices, is provided. Its long-shaped molecules are orientated perpendicularly to the electrode plates delimiting the crystalline liquid, i.e. homeotropically aligned. A polymer layer with long-chain molecules has been previously formed on the internal faces of each plate separately arranged on a discharge electrode of an electrical apparatus operating at high frequency (13.56 mc/s) and containing a vapour at very low pressure of a monomer such as hexamethyldisiloxane. The molecules of polymer thus formed are perpendicular to the plates and a similar orientation of the liquid crystal molecules result from that, i.e. a homeotropic alignment.

    摘要: A process rendering certain electron masking resins more sensitive or rendering polymers which are unsufficiently sensitive to electrons suitable for industrial utilization, in particular for application to electron masking, a method which employs scanning with a very fine electron beam controlled by the computer. The process involves electron irradiation at low dose levels, sufficient however to create free radicals, followed by diffusion of an appropriate copolymerizing monomer by grafting to the initial polymeric chain opened by the irradiation process. The solubility of the copolymer vis-a-vis certain solvents is selective, enabling the masks to be developed.

    摘要: The invention pertains to a method for metallic coating according to which the fiber is made to pass through a bath of molten metal. To prevent unevennesses in coating, caused by turbulence, a depression is made above the bath.The invention also pertains to a device by which the method is applied. The fiber goes vertically through a pot containing the molten metal above which the depression is made.The invention can be used to make optic fibers of greater mechanical strength.
